Letters Patent No. 95,514, dated October 5, 1869.

lMIROVEMENT IN CHURN-D-ASHERS.

The Schedule referred to in these Letters Patent/and making part of thename I A A ends, because theydescribe a larger circle.

To all whom it may concern:

Be it known that I, GUsTAv RADBRUCH, of Hoboken, in the county ofHudson, and State of New Jersey, have invented a new and improved Ghurn-Dasher; and I do hereby declare that the following is a full, clear, andexact description thereof, which will enable others skilled in the artto make and use the same, reference being had to the accompanyingdrawings, forming part of this specification, in which- Figure 1represents a sectional side'view of my improved churn. g

Figure'2 is a plan or top View of the same.

Similar letters of reference indicate corresponding parts.v Y

This invention relates to that class of churns known as atmosphericchurfns; and

It consists in the arrangement ofthe inclined tubes with. relation tothe dasher.- These tubes are supported upon the dasher, with their upperends nearest to the same, whereby, during their operation, their lowerends will move much faster than their upper The suction produced at thelower ends of the pipes, as they pass through the cream, will causetheair torrush with great rapidity into the upper ends, which would not bethe case were both ends of the tubes equidistant Afrom the shaft. By myarrangement, centrifugalforce is applied, by' which the air in th upperends of the pipes receives an outward motion, thus causing it to followthe direction of the pipes into the cream.

A, in the drawing, represents the vessel'or churn. B is its cover.- i Cis avertical central shaft, tted through the cover,

and supported by a step, c, on the bottom of the churn. It can receiverotary motion byy means of a crank or other suitable mechanism.

From the shaft O 'project arms or braces, b b, which serve tosupport twoor more tubes, D D, which ,con-l 'stit-ute the sides ofthe dashei, andwhich are, bypreference, placed in inclined positions, as shown ininfig. 2so that the lower openings of the tubes will be drawn away-from,and not pushed against the cream. The horizontalvlower parts of thetubes will thus, when they are drawn through the cream, leave a vacuumin their track, `which is filled by air enteringv through the tubes.

The cover B should be perforated, to -allow air to enter the tubes D. f

Having thus described my invention,

I claim' as new, and desire to secure Patent- A -The dasher hereindescribed, consisting of the central shaft C, arms b b, and straighttubes D, the lat` ter being inclinedinwardly, from bottom to top, andhaving an elbow formed at their lower ends, as and for the purposespecific,
